UCLA Researcher Prepares New Wave of Neuroscientists for Big Data, Machine Learning


 
UCLA Dr. Mark S. Cohen has trained thousands of students, graduated nearly thirty Ph.D. candidates and helped revolutionize the way we connect the mind and the brain.

"My college roommate was a philosopher," so goes the story of Dr. Mark Cohen, but Cohen's isn't one that involves a premature existential crisis nor is it the typical hellish-roommate tale. On the contrary, engaging in philosophical discussions as an undergraduate helped spark Cohen's interest in the human brain. 

A professor-in-residence at UCLA's Semel Institute for Neuroscience and Human Behavior and the creator and director of the Semel Neuroimaging Training Program, Cohen has helped forge revolutionary advancements in his field including functional magnetic resonance imaging (fMRI) technology, which he helped pioneer in the early 1990s. 

Whereas conventional MRI is purely structural imaging, he said, fMRI completely changed the landscape. "Imagine the difference between taking a photograph of a house and doing thermal imagery of the house that shows the water flowing through the pipes," he said.

Cohen has also been on the forefront of computational neuroscience, which his alumni routinely employ while conducting research. Essentially, they utilize machine learning to run faster analyses on the brain by using the Hoffman2 cluster, a supercomputer with enormous databases hosted at IDRE.

Dr. Ariana Anderson, Dr. Don Vaughn, and Dr. Wesley Kerr are three of his alumni. Read more.

A Picture of the Energy Landscape of Deep Neural Networks


Monday, February 5
11 a.m. to 12:30 p.m.
EE-IV Shannon Room #54-134


Abstract: Deep networks are mysterious. These over-parametrized machine learning models have hitherto defied attempts to put a sound theoretical footing beneath their impressive performance. This talk will shed light upon some of these mysteries. I will paint a picture of the training process of deep networks. Along the way, I will develop state-of-the-art algorithms for non-convex optimization. I will conclude with a vision of how advances in machine learning and robotics may come together to help build such a Cyber-Physical Intelligence.

An Informational Perspective on Uncertainty in Control


Monday, February 5
12:30 p.m. to 1:30 p.m.
Mong Learning Center - EE-VI


Abstract: High-performance cyber-physical systems rely on many sensors and hardware components for successful operation. Control strategies for these devices require an understanding of how unpredictability in these components might impair performance. Can we quantify the value of adding an extra camera to our system to reduce uncertainty? In this talk, I discuss some theoretical perspectives to understand uncertainty in systems as well as practical protocols to mitigate it.

Speaker Bio: Gireeja Ranade is a Researcher at Microsoft Research, Redmond. She received an S.B. in EECS from MIT and an M.S. and Ph.D. in EECS from UC Berkeley where she designed and taught the pilot version of lower-division EECS classes.

6627 Math Sciences Building


Abstract: A century since the publication of Darcy Thompson's eponymous classic "On Growth and Form," his vision has finally begun to permeate into the fabric of modern biology. Within this backdrop, I will show how a combination of biological and physical experiments, mathematical models, and computations allow us to begin unraveling the physical basis for morphogenesis in the context of examples such as leaves, guts, and brains. I will also try and indicate how these problems enrich their roots, creating new questions in mathematics, physics, and biology.

Speaker Bio: L. Mahadevan teaches Physics and Organismic and Evolutionary Biology at Harvard University. He is also the Lola England de Valpine Professor of Applied Mathematics at Harvard. He uses experiments, theory, and computation to study motion and matter at the human scale, where phenomena are robust and easy to observe, yet not always easy to explain. His areas of interest include the patterns of shape and flow of inanimate matter on scales ranging from the supramolecular to the planetary, and the dynamics of sentient living matter that can self-organize, perceive and act.
